weak but constant strombolian activity continues
Update Mon 06 Dec 2021 18:14
Ongoing strombolian activity is now in progress from the South-East crater characterized by weak ash emissions extending to the E-NE of the volcano today.

A volcanic tremor has slowly increased, but remains at medium values detected at 2700 meters altitude.
No significant ground deformation was recorded.
strombolian activity started and may trigger paroxysm
Update Sat 04 Dec 2021 18:40
After a six weeks since the last strong eruptive episode (classified as paroxysm), it seems the activity to have picked up again.

The volcano observatory in Catania (INGV) reported that strombolian explosion started from the South-East crater at 16:10 local time today.
The instruments detected a strongly rising signal of volcanic tremor indicating rapid magma flux towards the surface, typical sign for an impending series of paroxysm in the coming days, weeks.
Weak explosions reported from Northeast crater
Update Sat 20 Nov 2021 17:49
In the past weeks, Etna has been more or less calm. Today, small intermittent explosions resumed at the North-East crater, the volcano observatory in Catania (INGV) reported.

According to a report, these explosions began at 11.16 a.m. local time and have been producing small ash plumes that dispersed quickly in the area of the summit craters. Volcanic tremor shows no significant variations and remains at low to medium levels.
Apart from this, the Bocca Nuova seems to be the most active crater at the moment, producing dense steam plumes with some pulsating activity as can be seen in the image attached.
Occasional ash emissions from SE crater
Update Thu 28 Oct 2021 18:49
After last Saturday's paroxysm, the volcano has not remained completely calm, but produces ash emissions from the New SE crater from time to time.

Volcanic tremor is at low to moderate levels, something that can change any time.
Etna volcano (Italy): violent eruptive episode, parts of SE crater collapse into dangerous pyroclastic flows

A strong paroxysm is in progress at the volcano. As suspected already last night by the presence of intermittent strombolian activity and the slowly rising tremor, this activity continued to evolve gradually throughout the night and early this morning.

Tremor reached high levels at 7.40 a.m., followed by a strong increase of explosive activity at the SE crater from 10.15 a.m.
Lava fountaining was observed to have started at around that time, and lasted until 12.20 p.m. It generated a dense ash plume that rose several kilometers and drifted east, producing ash falls in the area of Piedimonte and Linguaglossa.
The eruption was characterized by several collapse events on the eastern sides of the crater, which generated pyroclastic flows - hot turbulent avalanches of loose lava material, and extremely fast-moving and dangerous as everything in their path is being destroyed.
The first was observed at 10.49 a.m., when parts of the eastern crater wall broke into an avalanche heading towards the Valle del Bove and traveling about 1.5 km distance. Additional pyroclastic flows with similar mechanism took place at 11.02, 11.30 and/or 11.37, and 11.58 a.m.
A lava flow was erupted from the breached SE crater heading towards the east into the Valle del Bove as well.
